hey guys its getting too hot so i need help!.
I have a 83 4ac sprinter, it has air conditioning but its not that cold.Like its working i can feel the cold air but compared to my friends old ford laser it crap. I just got it regassed but im not sure if he used the old gas or the new gas. Is there anything i can do to make it colder because man im getting cooked.
I have a 4ac engine. I also work as a mechanic 5 days a week. Anyway last year I totally re done my aircon last year. I had the same problem as you.
1. If your standing in traffic the aircon doesn't perform as well as if the cars moving. That means the compressor is weak and changing it will help.
2. There is a Black / sometimes Silver canister normally located in the front of the car (next to the radiator somewhere) On my 4ac its located directly under the coolant reserve tank. This canister should be changed ( if it hasen't been changed in the passed approx 4 years or so) to give better flow of gas i.e cooler air.
3. The condenser which lookes like a radiator but in fact sits righ in front of the radiator. Make sure there is no bugs / leafs stuck in it. Give it a spray with the hose.
4. Mare sure that when the aircon is switch on that both thermal fans turn on.
5. I had a 3rd fan installed on the condenser to allow better cooling of the condenser. The colder the condenser is the colder the aircon is.
6. And finally make sure there is a adequate amount of the proper aircon gas in your system, and that you have no gas leaks.
The two main that contributed to a better aircon were the type of gas in the system and that canister I was talking about. I would check these out first.
P.S The old type of gas is much better than the new type. The only thing is. It's way more expensive, but worth every cent.

Maybe not in this case....

Sprinters don't have thermo's.. Clutch only with the 4AC
On the Air con box of the sprinters you will see a black box that adjusts when the compressor is activated at what RPM. The Sprnters out of the factory will not turn on at idle. As soon as it is at idle the compressor switches off.. You can change that by adjusting the knob on the black box..
Just start the car, turn on the aircon and then turn the knob to "-".... You will see and hear when the compressor kicks in.....
But bare in mind... that when you do these two things...
1. These cars do not have a idle up... Yours RPM will drop..
2. If left like this for long periods of time on a hot day in traffic... IT WILL OVERHEAT!!!!
